This bit controls the USB's response to IN tokens from the host. Set at Reset and on an EOT event
and must be cleared by software when the last byte of a transfer has been written to the IN-FIFO. This
bit is then subsequently set by the USB core when an end of transfer (EOT) event occurs, indicating
that the transfer has been completed. An end of transfer (EOT) event is indicated by one of the
following:
a) An IN packet is transmitted that contains less than the maximum number of bytes defined at
b) A zero length IN packet is transmitted. This occurs when the previously transmitted IN packet was

Force STALL response. Causes the endpoint to return a STALL handshake when polled by either IN
or OUT token by the USB host controller. The STALL handshake causes the endpoint to be halted.
The STALL bit is not valid for isochronous endpoints. This command bit is write-only and always
returns 0 when read.
